The most precious thing of the Golden Toad is the negative pressure thruster.

The scientific and technological content of the negative pressure thruster itself is not unattainable, but the most critical negative mass substance must be created at the peak of the neutrino era.

In other words, as long as there is a negative mass matter, even an entry-level civilization in the atomic age can build such a thruster that specializes in navigating wormholes.

It is almost difficult for humans to understand what negative mass is.

But it's actually quite simple, it still respects the laws of mechanics in the inertial frame, except that it moves in the opposite direction to the positive mass. If you push the negative mass forward, it will accelerate the regression.

Not only that, but its gravitational pull is also negatively expressed, i.e., it becomes repulsive.

When this substance comes together, it creates a strong negative pressure, which is tension.

If you can tear yourself apart in an instant, if you don't have enough restraints, the place that was originally this substance will dissipate into a vacuum......

This is also the reason why after the birth of the universe, only matter can be seen, but no negative mass matter can be seen, because even if they are born naturally, they will dilute themselves into formless from the moment of birth...... The ends of the universe have a grain-like density at each end, and finally drowned in countless matter.

But if there is enough technology, it can still be made and constrained. At this time, the place where the negative mass matter that is fixed together has a strong negative energy, and the reverse warping of time and space.

The negative mass repels all positive matter, so it looks like a vacuum, but it has a strong repulsive force, distorting space-time, like a bulging space-time.

Defining a vacuum as the degree of distortion is zero, then as the mass of the matter in it increases, its 'depression' will be greater and the gravitational pull will be greater.

This is positive mass, which is the case with all matter in the universe, even dark matter has mass, causing space-time to sink.

But if space-time is negatively depressed, or 'bulging', then it is defined as having a negative mass.

The space-time that carries negative mass is called a negative vacuum.

Negative energy vacuum is hardly born for too long, and is often a very microscopic point, fleeting.

Because the universe is full of matter and energy, they fill in all the places of negative and low energy states.

It's like an ocean, all the water fills the valley.

However, the spatial scale of the universe is not only three-dimensional, so the sea does not actually fill all places.

There is an earth below the ocean, and a sky above the sea.

If the sea surface is sunken, that is the gravitational field, if the depression reaches the extreme, the conical vortex breaks through the seabed and burrows into the earth's crust, it is the singularity.

On the contrary, the sea surface rises into the sky, like a mountain of water bursting into the atmosphere, which is the repulsion field, which is converted into a negative energy vacuum in the universe.

If this mountain is connected to another mountain, then it is called a wormhole.

So theoretically, there are two ways to transition time and space, one is to use black holes to penetrate the 'crust' and penetrate to the other side of the world, and drill a white hole from another part of the cosmic ocean, but this is too difficult, and people and things will inevitably be destroyed.

The other is to create two 'mountains above sea level' and jump from one wormhole to another, which can transport organisms.

Of course, the universe is not really simply an ocean, it is a multi-dimensional supercube, so it sounds as if the way the two mountains are connected seems to be farther away, but in fact it can be very close, like a door.

It is known that this is the mainstream interstellar mode of interstellar travel in the universe.

Even people with low technology such as earthlings can use mathematics to prove its feasibility.

But understanding is understanding, there are only two civilizations known to the galaxy that can create stable, commercially available wormholes.

However, the neutrino-level civilization cannot create a wormhole, but it can create a stable negative energy vacuum, and can build its own negative pressure thruster to use the wormhole.

Atomic civilization, neither of which can be built, can only buy negative energy vacuum balls, and then build negative pressure thrusters around it.

Even worse low-level civilizations with nanotechnology can't build thrusters, so they simply buy a negative pressure thruster made by others and install it on their own spacecraft.

This ladder, which naturally arises because of technological differences, is a chain of exploitation.

The lower the civilization, the more expensive the goods will be, and the higher the cost of the jump.

Negative pressure thruster is a 'just need' in interstellar civilization, and wormholes cannot be used without it, which is almost a necessary thing for transstellar spaceships.

Therefore, although there are only two major civilizations in the galaxy that can build wormholes, there are countless companies that can produce negative pressure thrusters, with many brands and uneven quality of strength and weakness.

If the lower civilizations in the universe have just joined the Star Alliance, they belong to the exploited class.

Then the earth is not even qualified to be dumped by goods, this kind of thruster can't be bought, even if the wormhole is placed in front of you, it can't be used, and if you hit it directly, the plane will be destroyed and people will die.

"So anyway...... I'll have to take a negative vacuum ball too. ”

"This thing is not something we can build at all, even if we have the technology, we can't build it, the conditions are extremely harsh. ”

Huang Ji said, after transmitting the information of the spaceship, he falsified the data on the state of the aircraft.

Then he came to the place where the negative pressure thruster was located and took one of the negative energy vacuum balls inside.

"Is this really going to go undetected?" Fez asked.

Huang Ji said: "There are a total of two negative energy vacuum balls in this thruster, I took one away, everything is normal under normal conditions, and the system also shows that there are two in it under my forgery." Even if the wormhole jump is performed, it will not be discovered, because one is enough, and the other is just a backup for the Golden Toad. ”

Fez nodded and said, "With it, we have hope of leaving the solar system." ”

"Even if it is discovered, you have to take it! You can die as many people as you want for it, and if you want me to say, try to take the weapons on the moon as much as possible, and there is nothing that can be done without sacrifice. ”

Huang Ji stared at Fez and said, "Once they suspect that the earthlings have stolen something and escaped, it is not as simple as a dead person, they will gradually know everything when they kill the people of the Illuminati and Kunlun Ruins, and then send someone to hunt me down." ”

"The end result will not be to sacrifice a group of people to successfully send me out. It's that all the rebels are still dead in vain, and the human race will have their legs broken again......"

Fez muttered, "You're a little too steady. ”

Huang Ji smiled: "It's that you're still used to luck." When the technical gap is too big, the other party doesn't know that there is an enemy like me, which is the best. Once you know, even if it's just a little bit, it will end up like an anthill. ”

Fez said, "I just think that if you bring more good things on the road, it will be easier to mix in the interstellar world." ”

"No, that's just going to make it hard for me. I started with a ship, and that's enough. Huang Ji smiled.

......

"Hoo ......" Famuli climbed to the level of the weapons warehouse with difficulty, holding an alloy feather knife in his hand.

Previously, the cigar flying chair was controlled by 'Daddy' and lowered to the bottom.

But that didn't stop the bear child, who jumped out of the air and hung himself in front of a room in the twist passage, and then climbed up with his tenacious will and arm strength.

Famuli is a mixed-race little gray man, although he is only three years old, he has the strength of S1, he can blow up the head of a cow with one punch, tear the lion tiger with his hands, and fight the bear alive.

"Damn, if you can't fly, this passage is too difficult to climb......" Famuli lay on a smooth, curved surface, and with a feather-like alloy knife, he stuck into the gap in the wall decoration, careful not to slide down.

"Daddy is wearing a mech, this is a fierce enemy! I have to help him!"

Famuli continued to climb upwards into the weapons warehouse, which was empty, and the most striking thing was a large black ball.

This is the so-called warehouse, which is actually a factory, just like the material warehouse.

It's just that the refinery upstairs is upstairs, and the weapons processing plant is below.

Unless it's a time of war, it's all about making something temporary, not making a lot of it and putting it to waste.

"Well, I don't have the money...... Famuli glanced regretfully at the workshop door of the 'custom weapon', then ran to the other side, found a black wand that Dees had made and thrown here, and took a set of the colonization outfit that Dees had used in the early years.

Soon, wearing white armor, a black wand in his left hand and a feather knife in his right hand, he excitedly rushed out of the arsenal and flew up to the upper level with his breeding suit.

As a result, he had just flown far when he heard a rapid alarm bell ringing.

This sound will make the little gray man feel extremely alert, the relevant hormones are secreted wildly, the attention is highly concentrated, and the body's movement state suddenly rises!

"This is a street fighting alert! The enemy has come in, into the core?" said Famuli.

Dees told him that this was the last alarm on the moon base, and if it was triggered, it would mean that they were all forced to the point of a decisive street fight.

At this moment, the strength of their Zeta clan will increase, because this special alarm sound wave will stimulate their body, keep their fighting spirit high, and transmit biological energy to them in the form of sound waves!

In this way, it is equivalent to hanging a bioelectric auto-charging state in battle.

He had only heard such an alarm from Dees, but he had never experienced it.

Now that I heard it, it means that the enemy this time is not trivial.

"I'm going to help Daddy!" Famuli sped up.

But suddenly, the passage above his head bloomed with a strong golden light, and a silver-winged figure stumbled down in the passage!

"Ahh

But the fall of the Silver Wing Mecha is too great, and if it hits him, it will definitely die.

I saw the Silver Wing Mecha shouting angrily: "Silly boy, get out of the way!"

He threw him in the air, and a shockwave sent Famuli flying and crashing into a machine room next to the passage.

The Silver Wing Mecha continued to fall downward, hitting the bottom floor.

"Boom!" came the earth-shattering roar.

Famuli looked confused, and then reacted that his father was bombarded, and he quickly jumped down and stumbled to the bottom.

"How's it going, Daddy!" he said to the Silver Wing mech lying on the ground, helpless.

After all, he was too young to know how to deal with the situation where his father was knocked down.

"Vistio, I asked you to protect my brother and hide, why don't you obey!" Vis, of course, was in the Silverwing mech, and he roared as he struggled to his feet.

"I ...... I ......" Famuli said aggrievedly, pointing to the lowest room, "my brother is still sleeping." ”

"Get in there and hide!" Fez, holding up his thick shield and soaring into the air.

Famuli was lifted by the strong wave of air, and he fell to the ground, looking up.

But soon, he heard the desperate voice of his 'father': "What!"

I saw a scarlet round wall above, advancing along the passage.

Like the air in the veins, this cloud of scarlet energy, annihilating everything it passed all the way, as if the piston was about to push it to the end, wrapped in terrifying pressure, and slammed down on the head.

"It's over......" Fez fell back to the bottom, and there was no way back now.

He quickly grabbed Famuli, opened the hatch, and threw it beside his brother Visio.

Visio had already woken up, looked at his 'father' and brother with a blank face, and said with a milky voice: "My brother is hungry, and my brother wants to eat sharks." ”

"Use the first person when talking to people!" Fez's corrected in an angry tone, and then said in a frustrated tone, "Vistio, listen to my brother in the future." ”

"And you Famuli, learn to be patient, and my brother Omazo will take care of you. ”

"If he dies in the future, go to Earth to find Fez. Remember, don't tell anyone, or the earth will be destroyed. ”

With that, Fez closed the hatch and locked it.

Famuli pounced, desperately trying to open it, but he couldn't get past the authority of Dees.

"Daddy, you're hiding in too!"

Although he shouted like this, he also knew that the enemy would not give up if he could not find his father.

The enemy didn't know about the existence of the two brothers, and Daddy wanted to sacrifice himself to protect them.

"Uhhhh

He suddenly thought of something, and hurriedly clicked on the wall to draw a symbol, and the next second the scene outside the door appeared on the wall.

I saw that the terrifying scarlet light wall had been crushed down, and the Silver Wing Mecha couldn't resist it even if it was fully propped up by its shield.

"Ah!" Famuli screamed frantically slamming the door.

There was a scarlet glare on the screen, and I couldn't see anything clearly.

By the time the light had faded, Daddy was already lying on the ground, and the mechs were cracked open and emitting scorched smoke.

Immediately after, a tall crimson bird man landed and stepped on his father.

The feathers on the birdman's body were scarlet and fluttering, as if burning.

I saw him with his back to the hatch, stretching out his hand and pulling Daddy out of the mecha.

From Famuli's point of view, he could only see the lower half of his body, but he couldn't see his father's face.

But soon he will be able to see it, because the birdman tears his hands apart!

"Poof!"

Under the splash of blood, the birdman lowered his right hand, and the head he was carrying was none other than Dees.

"Ahhhh

But his shouts were completely soundproofed and could not be heard in the room.

The birdman casually threw his head down and flapped his wings and flew away.

Famuli could only see some of the ashes scattered down, as if the hateful birdman had incinerated Daddy's body again.

"Damn! damn birdman!"

Famuli's lungs were about to explode, but he was too weak to do anything.

The younger brother Vishio was also stunned, looking incredulous that his invincible father was gone.

Famuli turned around suddenly, grabbed his brother with both hands, and cried, "Daddy is dead!"

"Brother, we're the last Zeta!"
